Title: Supercharging pressure control device for engine with supercharger
Inventor: NAKAGAWA SHIGERU
IPC: F02B37/18
Filed: 1993-01-26
Abstract: PURPOSE:To provide constantly excellent control responsiveness even when an integrating item is arranged as a constituting element for a feedback control amount, in an engine with a supercharger formed in such a way that feedback control is made on a supercharging pressure under specific conditions. CONSTITUTION:By performing duty control of a control pressure fed to an actuator 14 coupled to a waste gate valve 12 to regulate a supercharging pressure by using a duty solenoid valve 15, the opening of the waste gate 15 is regulated. In which case, when a target supercharging pressure being deviated from the operation range of the waste gate valve 15 is set, a value obtained by subtracting a base duty value and a voltage correction duty value from, for example, a duty upper limit value is compared with 0, one, being larger, of the two values, whichever it may be, is selected as a final feedback duty value.

Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To secure originality of a peripheral device requiring no installing operation by performing communication with an external electronic equipment via a home bus, requesting the electronic equipment to transmit the user interface information necessary for the control of the electronic equipment, and storing the user interface information. SOLUTION: When an AV equipment 121 is purchased and installed, the equipment 121 is connected to a PC module 1 via a 1394-cable 6. Then the user interface information which has been previously stored in the equipment 121 is transferred and stored into the module 1 via the cable 6, when the module 1 performs its control. As a result, it is not required to give the software to the module 1 for its control, when the equipment 121 is installed. Transferring of the control software enables operation for even a module that has been added for the addition of new function.

Title: Inverter device
Inventor: TANIFUJI HITOSHI
IPC: H02P27/06
Filed: 1989-02-10
Abstract: PURPOSE:To prevent the stopping of an induction motor even if excessive load variation occurs by comparing an input current with the maximum allowable current of an inverter section and, at the same time, the varied value of the above-mentioned input current when the output of the inverter section varies by a prescribed quantity with a preset reference value for variation. CONSTITUTION:When this inverter device is operated under a normal condition, the input current Iin of the inverter device 5 is controlled even when the frequency of an induction motor 6 varies. At abnormal time, the input current Iin inputted to the inverter device 5 is compared with an input current value (I2) stored in a microcomputer 14 and, when I2<=Iin, it is discriminated that an abnormal state occurs. When the abnormal state occurs, the plus of the voltage of a compressor is repeatedly controlled to I2>=(A). When I2>=Iin, the voltage applied across the compressor is made to plus so that ¦Iin-Iin-1¦ can be controlled to a level lower than a specific value.

IPC: G11B11/10
Filed: 1995-01-30
Abstract: PURPOSE: To perform the positioning of a disk type recording disk easily, exactly and promptly by linearly approximating two best read-out positions obtained on the outer periphery side track and the inner periphery side track of a disk and relatively moving a test head in the radial direction of the disk along the straight line at the time of the test. CONSTITUTION: Writing signals are written into two tracks on the outer and inner periphery sides of a magnetic disk 1 by means of another writing head. The magnetic head 27 of the test head 23 is switched at each position in Y- direction by a Y-motor 16B where the magnetic head 27 is swung in X-direction by an X-motor 16A to scan the inner and outer tracks and to read the written signal. The reading operation is repeated at each position in the Y-direction. Then, the position where the maximum read-out output or the best read-out isolated wavelength width is obtained gives the best detecting position. These positions are determined in the respective tracks on the outer periphery and inner periphery side tracks of the magnetic disk 1.
